LINTEL -Applicatlon filed June 8, 1921. Serial 1T0. 475,937.

This invention relates'to metal beam suprts, and more particularly itrelates to a E am of a predetermined design ca able of a particular. anddefinite use in buil mg con- 5 structions.

One of the objects of this invention is to provide a unit metal beamhaving a portion thereof designed to support a ma n load and anotherportion designed to support another part of the load in a particularmaimer.

Another object is to provide a unit beam, which has a special use as alintel for door andwindow openings in building structures, and which hasan integral portion thereof of proper size and contour to support facingdesirable to employ metal beams as lintelsfor the door and window openins, as the other types of beams sag or ben thereby permitting the wallsto crack and split open thus giving entrance to the weather elements.Heretoforemetal beams have not been employed for this purpose to anextent commensurate with their desirability as they have only beenconstructed with a view of obtaining sufficient strength. Another reasonfor not employing the metal beams of prior construction is thatthey havenot been formed so they willsu port a facing ma terial. These objectionsl'iave been overcome by the resent invention which is directed to a novebeam construction which incorporates certain desirable practicalfeatures as well as being of proper strength.

In the accompanying drawin s which form a art of this specification, tere is illustrate a selected embodiment of this invention wherein,

Fig. 1 is a view in perspective of a portion 0L a beam of thenovelconstruction.

' material.

Referring to the drawings and particularly to Fig. 1, a beam of the newconstruction is illustrated as being a unit member having a web portion1, flanges2 and 3 integral with the web and extendin therefrom on thesame side, and a third ange 4.- also integral with the web and extendingfrom the opposite side of the web. In this preferred con-- struction thebeam is formed so that the main or direct load is carried by the portionof the beam comprising the web and the flanges 2 and 3, while the flange4 supports another and much smaller load which is the facing However itis to be understood that the flange 4 may be formed to materiallyincrease the strength of the beam as well as performing its specialfunction of supporting its load in a predetermined manner.

- Usually the beam is rolled from a steel ingot or bar.

This beam has, among'its several uses, oneparticular and specific usewherein 1t meets.

a need which has been present for a considerable length of time, andwhich has not been fulfilled by an article meeting the functional Irequirements as well, as beingof sufiicient strength. This new type ofbeam is readily manufactured at a cost substantially less than otherbeams which might be constructed to meet the need. This specific andparticular use is that of a lintel in building con struction wherein theflange portion 4 is particularly adapted to readily support the buildingor facing material covering the beam to have the material align'with thecontour of the building and to have this material placed in properposition without being cut or trimmed or required to be specificallyformed to fit a particular contour of a beam.

In the old building construction, the common I-beam has been employed asa lintel, but in such instances the external face of the beam has beenleft exposed to the weather thereby making an unsightly buildingcontour, or other and special materials have been employed to cover theexposed face of the I beam. In the last instance material other than themain construction material have been employed: to cover the beamand tomakethe building contour even. For in- .stance when the vexteriorsurface of a build building contour in the event that it could besupported on one of the I-beam flanges.

In the specific use of the beam illustrated a brick without requiringthe same to be trimmed or specially fltted to the flange. A beam of thisform when specifically employed as a lintel, permits the facing materialto be quickly placed in position on the flange, and in line with theexterior surface of the building contour. It is to be understood thatthe flange 4; may be of any desired design which will allow thefacing'ma terial to be easily and quickly placed in position and held inline with the building .contour.

Certain modifications may be made in beams which include the foregoingadvantages, and reference is made to Figs. 2, 3 and 4. showing some ofthe modifications. In Fig. 2 there is illustrated a beam having a tongue'5 which acts as an abutment for a door frame or a window sash. Thistongue also functions as a stop to prevent the weather elements frompassing directly between the base of the beam and the window sash. InFig; 3 a form of beam is shown wherein the flange 4 is located in aplane below that of the plane in which flange 3 lies. Vvhen the flange 4is offset, a face 6 functions as an abutment for a door frame or windowsash. The flange in oflset position also functions to prevent theweather elements from passing to the interior of the buildingconstruction in the same manner as tongue 5. It is to be understood thatmodifications of the tongue 5 and of the base 6 which act as abutnientsmay be made but that such modifications should give irregular contour tothe under side of the base of the beam and which modifications are soformed as to receive a construction article in a manner to maintain thisarticle in desired position and to assist in preventin the passage ofweather elements between the article and the building construction.There is illustrated in Fig. 4 a beam which takes advantage of thestrength of flange l to increase the total strength of the beam whilethe top surface of this flan e is still maintained substantially perpendlcular to the web in order to properly support the facing material.Such a beam has its strength balanced by increasing the size of flange2. l

Specific application of the improved-beam to a brick building structureis illustralcd in Figs. 5 and 6. In Fig. there is shown a sectional viewof a brick wall showing the ends of an I-beam and my improved beam attheir points of support. One form of beam embodying this invention isshown at 7 with the flange 4 resting on the brick -work and theflange 3on the usual plate 8 width of the flange is substantially that of thewidth of a brick and therefore the brick 10 for facing the beam areeasily placed in position and are held so the centcrline of this facingmaterial is parallel to a vertical plane passing through the web of beam7. By having the top surface of flange 4 substantially perpendicular tothe web, the brick employed as the facing material are placed inposition without being specially trimmed and they conform to the contourof the building outer surface. The space between the beams and otherspaces which are later covered by wall paper or the like, may be filledwith concrete or like material.

Fig. 6 shows in section the construction over a window opening andillustrates the particular use of the beam as a lintcl which supportsthe super structure, the facing material, and receives a window frame 12against face 6. A portion of a window sash 13' is shown in positionco-operating with the frame 12. With this design. of beam for use as alintel it is to be noted that rain water in passing down the facingmaterial will not pass to the interior of'thc window frame as it willdrop from the'lowcr side of flange 4: or will pass over the externalsurface of frame 12 and down on to the window glass. In thi connectionit is also to be noted that dirt and dust will not be blown to the innerside'of' the building or window as the window frame sets snugly againstthe lintel.

lVhile the preferred type of beam has been described for a particularuse, it is to be understood that it may be employed for other uses asfor example, a duplicate beam may be placed at the inner edge of thewall with the flange 4.- extending to the interior of the building sothat it may be employed as a support for the ends of girders.

Other uses and modifications may suggest themselves, but they areconsidered as being within the scope of this invention as outlined bythe following claims.

What is claimed is:

1. An article of manufacture being a beam integrally formed and havingtwo strengthening flanges and a third flange, one of said strengtheningflanges being at the top of said beam and the other two flanges being atthe bottom thereof, said beam having the under side of its baseconstructed of irregular contour between the edges of the two lowerflanges to form a holding means for receiving and positioning anotherarticle of building construction.

2.
